I've skated in rain and snow on well-worn AD07s and decided that with the S/C it deserved better for daily all-weather driving. I'm using Sumitomo HTR Z IIs on Rota Slipstreams (205/45R16 83W on front, 245/40R17 91W on back). This combination gives the same size height and revs per mile as OE within .02% and doesn't confuse the ABS.My AO48s were good in the rain until they became worn, now I need to replace them so I'm a bit more cautious when in the rain. I was really cautious when in the snow.
Even so, I still think if you'll be street driving in the rain a lot you should consider a street tire instead of a performance tire.
